- The internal notion of an "OID" or "ROWID" column has been
removed.  It's basically not used by any dialect, and the
possibility of its usage with psycopg2's cursor.lastrowid
is basically gone now that INSERT..RETURNING is available.

- Removed "default_order_by()" method on all FromClause
objects.
- profile/compile/select test is 8 function calls over on buildbot 2.4 for some reason, will adjust after checking
the results of this commit
